[nsp] 3750 limitations?

[Deepak Jain]

We are trying out a new 3750G-24-TS-E, and while trying to see how many BGP
routes we can feed it, the CPU falls on its face at about 20,000 routes.
Memory and such is fine. Are we just filling the RIB? Is there a good reason
why this thing would have enough memory for a full table but not be able to
take a full table?

The console logs these errors:
